IMPROVED WAGON-BRAKE. --4.

The Schedule referred to in these Letters Patent and making part of thelame.

T 0 all whom it may concern Be it known that we, GEORGE WESLEY WELsH andGEORGE WYLHJ, of Arlington, in the county of Oolumbia, and State ofWisconsin, have invented a new and improved Wagon-Brake; and we dohereby declare that the following is a full, clear, and exact descrip--tion thereof, which will enable others skilled in the art to malge anduse the same, reference being had to the accompanying drawings, formingapart of this specifi-' cation. 1 Y v This invention relates to a new andimproved automatic brake for wheel-vehicles and It consists in thearrangement of the parts of the brake with relation to the wheels, thehounds, and the bolt for attaching the pole to the hounds, as will behereinafter more fully described.

In the accompanying sheet of drawings- Figure 1 is anoinverted plan ofour invention;

Fi'gure 2, a side sectional view of the same, taken in the line as w,fig. 1.

Similar letters of reference indicate correspondingparts.

A represents an axle, having awheel, B, fitted loosely on each end.

I C G are hounds, between the front ,ends of which the draught-pole D issecured by a bolt, E, as usual. These parts being of ordinaryconstruction, donot require an extended description.

The bolt E, of the draught-pole, has secured upon it a rod, G, which isbent in such a form as to have V a central pendent projection, a,extending below the draught-pole, the rod G being fitted on the bolt Ein such a manner that it may turn freely thereon.

To, the lower end of the projection to, a rod, H, is attached, whichextends along, underneath the draughtpole, to nearly the front end ofthe same, where it is formed or provided with a loop or ring, I), whichis fitted and allowed to move freelyback and forth on the draught-pole.

Tothe ends of the rod G there are attached arms,

I' I, which extend back through suitable guides, c, to a.

shaft, J, the latter having a shoe, K, at; each end of it, said shoesbeing at the rear of thewheels B B, and in line with the same:

' The shaft J has spiral springs, d d, upon-it, which springs have atendency to keep the shoes pressed towards'the wheels, the shaft J'beingallowed to turn in the rearcnds of the arms I I.

; The'lioldback straps of the team are attached to the front end of therod H; and it will be seen from the above description, that when thevehicle is descending an eminence, and the team checked, forwardmovement of the vehicle will apply the brakes, and the shoes K are belowthe centres of the wheels, so that the latter will have a tendency, asthey rotate, to bind the shoes against them.

In case of backing, however, the shoes'will not press against thewheels, the retrograde movement of the latter having a tendency to throwthe shoes out from the wheels, as indicated in red.

This very simple arrangement of parts, constituting a self-acting brake,may be applied to almost any of the known forms of wheel-vehicles inuse, and at a very moderate expense.

Having thus described our invention,

What we claim as new, and desire to secure by Let- .ters Patent, is-

The arrangement of the bent rod G, having the pendent portion a,'thearms I I, shaft J, shoes K, spiral springs (land rod D, with relation tothe bolt E, the
